Hi all,
for many machines compilers are distributed by the machine
producers specialized for this machine (e. g. Sun sells a C-Compiler for
Sun 4). On the other hand generic compilers like gnu-c exist, which can
easily be changed for a new computer. The questions, which I want to ask
all compilers experts are:

* Which one is better in the aspects of code size, execution time and
effective use of resources and possibilities like delay slots and
processor caches?

* Is it possible to answer this question globally or is it necessary to
check each compiler on each machine?

* Do statistics exist and where can I get them from?

* How far are (hard) real-time considerations taken into account? (I
think of aspects like precalculation of execution time or at least
haveing always the same execution time for the same code.)

Waiting for your answers (by e-mail, if there is enough interest, I will
post a summary) and greetings from Vienna/Austria
